Transanal haemorrhoidal dearterialization (THD® Doppler) is a surgical procedure involving Doppler-guided ligation of haemorrhoidal arteries to reduce arterial flow. With proximal Doppler-guided dearterialization, arterial ligation is achieved by introducing the proctoscope completely into the anal canal and lower rectum. In the present study, distal Doppler-guided dearterialization (DDD) is performed in the distal 2 cm of the lower rectum. Immediate and short-term results were evaluated.
One hundred patients with bleeding haemorrhoids, with or without muco-haemorrhoidal prolapse, underwent THD® Doppler procedure, using DDD of the haemorrhoidal arteries 2 cm above the anorectal junction. Mucopexy was performed in patients with haemorrhoidal prolapse.
The operation time was 20 ± 7 min for dearterialization alone (10 patients), and 30 ± 10 min when mucopexy was added (90 patients). Morbidity included: transient haemorrhoidal thrombosis (two patients); urinary retention (five patients); submucosal abscess (one patient). No patient complained of faecal incontinence. At a median follow-up of 7.3 (3-17) months, all patients reported an improvement in symptoms. No patients reported bleeding.
DDD of the haemorrhoidal arteries could be a simplified and more effective method of applying THD.
经肛门痔动脉结扎术(THD®多普勒)是一种通过多普勒引导痔动脉结扎以减少动脉血流的手术。近端多普勒引导去动脉化通过完全将直肠镜插入肛门和直肠下段来实现动脉结扎。在本研究中,在直肠下段 2cm 处进行远端多普勒引导去动脉化(DDD)。评估了即刻和短期结果。
100 例出血性痔患者,无论是否伴有黏膜痔脱垂,均接受 THD®多普勒手术,在肛门直肠交界处上方 2cm 处对痔动脉进行 DDD。对有痔脱垂的患者进行黏膜固定术。
单纯去动脉化的手术时间为 20±7min(10 例),加上黏膜固定术的手术时间为 30±10min(90 例)。并发症包括:一过性痔血栓形成(2 例);尿潴留(5 例);黏膜下脓肿(1 例)。无患者抱怨大便失禁。中位随访 7.3(3-17)个月,所有患者均报告症状改善。无患者报告出血。
痔动脉 DDD 可能是一种简化且更有效的 THD 应用方法。
